Comment 5 for bug 1517848

This bugs affect me too, after I did a clean install of Ubuntu GNOME 15.10. Was unable to color manage my screen, since both the Color-setting (GUI) and "colormgr get-devices" returns an empty list.

However, there is a way to make this work: Install and use "lightdm", insted of "gdm". This will enable you to color manage your screen. (Solution found here: http://askubuntu.com/a/699444)
